Greetings All, I'm trying to build a stepper motor driven indexer. The goal is to use the inherent accuracy of a stepper motor and encoder to index a wheel. US Digital sells an IC that uses the output from an encoder to generate step and direction pulses. These pulses can then be used with a stepper motor driver IC to drive a stepper motor. It works well until the stepper motor recieves pulses faster than it can move and steps are lost. If it's easy enough, and cheap enough, I would like to build some type of buffer that will accept the signals from either an encoder or the step and direction IC and output them at a certain rate that doesn't exceed the stepper motor's maximum step rate. Is this something that can be easily done by someone who is good at following directions, can solder well, but really doesn't know much about electronics? Any help would be great. Thanks, Eric R Snow
